A closer look
The deepest philosophical revelations often come from just being completely high in a dentist's chair. P.D. Ouspensky was an intense Russian esotericist who wrote heavy volumes on the fourth dimension and the illusion of time. To achieve these altered states of consciousness, he didn't rely solely on meditation; he frequently used nitrous oxide. He would huff laughing gas and feverishly write down his profound universal truths, only to sober up and realize he had scribbled utter nonsense. He eventually decided the universe's secrets just couldn't be captured in English.
